c++: duplicate block-scope extern [PR 97877]
We ICED with a duplicated block-scope extern, as duplicate_decls was
dropping the decl_lang_specific of olddecl. Simplys adding
appropriate retrofitting and copying turned out to be insufficient
because you can get a block-scope using decl also matching the extern.
The latter seems a little suspicious and I have asked CWG for advice.
While there robustified the assert about releasing olddecls'
lang-specific -- if it had one, the new decl better have one.

* decl.c (duplicate_decls): Deal with duplicated DECL_LOCAL_DECL_P
decls. Extend decl_lang_specific checking assert.
